Can Chickens Burp Or Fart? [An Interesting Topic]

Chickens are fun animals to own. Whether you own them as pets or use them for your livelihood, you can’t deny that they are fun to watch. Chickens are fascinating little birds and can provide entertainment for almost anyone. It’s not unusual to hear weird sounds coming from your birds, sounds that resemble a burp or a fart every once in a while. It might even catch you by surprise; can chickens even burp or fart? Birds have very different bodies than mammals. How are they able to produce gas?

Can Chickens Burp Or Fart

Yes, chickens can burp and fart. Chickens can swallow air while eating or breathing; some air comes back up and out through their mouth while other air makes its way through the gastrointestinal tract before being released through the chicken’s vent.

A Chickens Digestive System

A chicken’s digestive system is very simple, but it is also very effective. For birds to fly, their digestive system needs to be simple enough for it to be lightweight. Even though chickens don’t fly, their digestive system is similar to birds that fly.  

The chicken’s digestive system contains many parts. It starts at the mouth, then moves to the esophagus, then to the crop. The crop is where food is stored temporarily before reaching the stomach. Food can stay in the crop for up to 12 hours before moving on.

However, a chicken has a faster than normal digestive system, which doesn’t allow the food to sit in their short gastrointestinal tracts to ferment and form gas. That said, they will sometimes pass gas or fart, just not as much as us.

The stomach consists of two parts; one is the gizzard for grinding food, while the other is for storage. The gizzard breaks apart the food into smaller pieces so it can be processed easier. The food moves from the stomach into the small intestine, where food is better digested and where nutrients are absorbed; the small intestine contains the duodenum, jejunum, and ileum. Next is the liver, which aids metabolism.

The food then moves into the ceca, where bacteria help break down food before it passes into the large intestine. The ceca and the large intestine are where the gas inside of your chicken is made. The large intestine primarily dries out food and absorbs water.

Eventually, waste exits through the chicken’s cloaca and out the vent. Any gas created by the intestines will also be released this way. Chicken droppings are great as fertilizer and can be composted.

Why Do Chickens Burp

While a chicken is eating, it could accidentally swallow some air. Swallowing air is also known as aerophagia. It usually happens when eating or drinking too quickly. The gas then goes down into your chicken’s stomach.

Most of the gas should release itself naturally by coming up through your chicken’s esophagus and out through its beak. However, some of the gas might move along through its digestive tract. If this happens, it will pass out of your chicken’s vent rather than out through its mouth.

Don’t worry. Any gas swallowed by your chicken will make its way out eventually. If you notice your chicken burping a lot, it could indicate an underlying problem. 

Usually, this signifies an upper gastrointestinal disorder such as ulcers or gastritis. Yes, chickens can get ulcers like us. Seek attention from your veterinarian if you have any concerns. They might be able to help you find an effective treatment or prevention plan.

Why Do Chickens Fart

When a chicken swallows air, some of it gets absorbed into its digestive system. The digestive system also creates its own gas occasionally. Undigested food passes into your chicken’s large intestine, where it is broken down into smaller pieces using bacteria from the ceca. 

This breaking down process creates hydrogen and carbon dioxide. Sometimes it can create some methane gas as well.

Chickens with constipation, ulcers, or inflammatory bowel disease are more prone to gas, but some foods they eat can also cause more gas than usual. Foods high in sulfur, such as plant-proteins, are known to produce more gas.

The gas created in your chicken’s digestive tract ferment while inside and eventually releases through their vent. The gas produced by any animal will smell, but some foods can make it smell worse than usual such as canola seeds or soybeans.

Passing gas is a normal part of your chicken’s digestive system and shouldn’t be of any concern. If you notice your chicken passing gas more often than it should, it might be a good idea to check in with your veterinarian to see if there are any underlying health problems. Sometimes gas can be painful for chickens and cause some distress.

If you notice your chicken in distress from gas, you can try giving them some Epsom salt water to clear out anything in their system that might be bothering them. 

Epsom salt is an FDA-approved laxative and is perfectly safe to use for your chickens as well. You should also consider changing up your chickens’ diet. They might benefit from foods with less sulfur.


Chickens can burp and fart, and it can be amusing to hear. Burping occurs after your chicken has swallowed some air while eating, drinking, or breathing. The swallowed air is then released from the stomach by rising out through their mouth. Burping is normal for any animal but can be a problem if it occurs too often.

Farts happen when a chicken’s digestive system creates carbon dioxide, hydrogen, and methane gas. This gas ferments inside your chicken before being released out from your chicken’s vent. Gas is also perfectly normal for chickens but can signify an underlying problem if it causes your chicken distress.

Every animal with intestines will pass gas one way or another. Chickens have a very simple digestive system, allowing them to be light enough for flight, but it also functions very similarly to our own. 

It is perfectly normal for your chicken to pass gas, although it can be uncomfortable for them and smelly for you if you’re around. If you’re ever concerned about your chicken’s health, you should ask your veterinarian for advice.
